This  has been a very big week for Houston. The team called up the top-rated prospect in baseball, shortstop Carlos Correa, on Monday against the White Sox and he had a hit and RBI. On Wednesday, the team will debut one of its top pitching  prospects in Vincent Velasquez. Here's every game on Wednesday in order of start time and with opening BetOnline odds. Phillies RHP Jerome Williams at Reds RHP Jon Moscot (-140, 8.5): Williams has pitched more than five innings just once in his last eight starts, in which he has compiled a 6.81 ERA. His 63 ? innings among pitchers with 12 or more starts this season are the fewest in baseball. Moscot struggled early on in his Major League debut, but he improved after he calmed his nerves. Moscot gave up runs in each of the first three innings on Friday, but finished the game retiring 11 of the last 12 batters he faced. Marlins RHP Tom Koehler at Blue Jays RHP Aaron Sanchez (TBA): Koehler has had mixed results when facing the American League. In nine career Interleague starts, he is 4-2 with a 5.01 ERA and has given up more hits (54) than innings pitched (50 1/3). Sanchez was three outs away from recording the first complete game of his career in his last outing vs. the Astros but was pulled in the ninth. He hasn't allowed more than three earned runs in a start since May 13. Nationals LHP Gio Gonzalez at Yankees RHP Nathan Eovaldi (-123, 8.5): Gonzalez (4-3) took the loss despite giving up just two runs over six innings Thursday against the Cubs. He struck out six, walked four and allowed four hits. He's had a lot of start-to-start inconsistency thanks to a sky-high .372 BABIP, which should correct course in due time. Eovaldi has struggled against the Nats, with a 5.32 ERA in eight career starts. In his last outing vs. Washington on May 19, he gave up five runs in 4 1/3 innings, including home runs by Bryce Harper and Ian Desmond. Cardinals RHP Carlos Martinez at Rockies RHP Chad Bettis (+111, 10.5): Martinez has allowed just three runs over his last 32 1/3 innings. He is coming off a career-best 11 strikeout performance. He has made one appearance (in relief) at Coors Field and allowed four runs on five hits in 1 2/3 innings. In his last three starts, Bettis is 3-0 with a 1.21 ERA, has held opponents to a .165 batting average and has 19 strikeouts against five walks. Red Sox RHP Rick Porcello at Orioles Wei-Yin Chen (-115, 8): Porcello bounced back from a pair of rough outings with an eight-inning, two-run effort Wednesday, although he suffered his third straight loss. He has a 5.21 ERA in 11 career starts against Baltimore. Chen struck out a season-high nine and allowed just two runs on five hits over 5.1 innings Thursday, but received no decision in an eventual win over the Astros. Chen has delivered quality starts in six of his last eight games. Brewers RHP Kyle Lohse at Pirates RHP Charlie Morton (-143, 7.5): Lohse struggled again in his last outing, surrendering a five-run lead and taking an no-decision. The veteran is now 3-6 with a 6.59 ERA. Morton will seek a couple of career firsts: He has never begun a season 4-0, and has never won four straight starts. But he'll have to be sharper than in his previous start, when the Pirates offense picked him up in a 10-8 decision. Cubs RHP Jake Arrieta at Tigers RHP Shane Greene (-106, 8.5): Arrieta was brilliant last time out, tossing six innings of one-run ball in a win against the Nationals. He has 27 strikeouts compared to four walks over his last four starts. Greene, who has been in danger of losing his rotation spot, faces the Cubs -- a right-handed-heavy lineup. He has not gotten out of the fifth inning in his past two starts, lasting 4 1/3 against the A's on Thursday. Angels RHP Jered Weaver at Rays RHP Erasmo Ramirez (+100, 7.5):  Weaver entered Friday's game at Yankee Stadium with a 1.98 ERA in his previous five starts, then gave up seven runs on nine hits in 5 2/3 innings. Most of the damage came on three home runs that barely cleared the short porch in right field. Ramirez faced the Mariners Thursday and came away with his fourth win of the season, holding his former teammates to one run on seven hits and a walk in 5 1/3 innings. He is 1-1 with a 3.13 ERA in seven appearances at Tropicana Field this season. Padres RHP Tyson Ross at Braves RHP Williams Perez (+110, 7.5): Ross picked up his first road win of the season the last time out against the Reds, going five innings in a start that was shortened due to rain. It was the seventh consecutive start where he's allowed three or fewer runs. After three starts of at least five innings and no more than one run allowed, Perez struggled to command his fastball Friday against the Pirates. It led to his worst start of his brief big league career: four runs and five walks in five innings. Giants RHP Tim Hudson at Mets RHP Matt Harvey (-155, 7): Hudson has a long history against the Mets, due mainly to the nine years he spent with the Braves. He's 17-10 with a 3.52 ERA in 32 lifetime starts against them, including 5-2, 3.24 in eight assignments at Citi Field. Think Harvey likes pitching at Citi Field? He owns a 2.09 lifetime ERA there, compared to a 3.01 mark on the road. Harvey has faced the Giants twice in his career (both times away from Citi), delivering quality starts on both occasions. Mariners RHP Taijuan Walker at Indians RHP Trevor Bauer (-145, 8): After a rough start to '15, the 22-year-old has put together back-to-back eight-inning outings, including a scoreless, two-hit gem against Cleveland on May 29. Walker has a 2.51 ERA at Safeco Field, but a 9.79 mark in six road starts this season. Bauer (5-2, 2.94) has been on a nice run of late, pitching into the seventh in each of his past five turns. In that span, the righty has gone 3-1 with a 1.75 ERA, 36 strikeouts and 13 walks in 36 innings for the Tribe. Astros RHP Vincent Velasquez at White Sox LHP Jose Quintana (-130, 8.5): Velasquez, 23, is the Astros' No. 4-ranked prospect and is the second pitcher they have promoted within a month from Double-A. He went 3-0 with a 1.37 ERA in five starts for Double-A Corpus Christi. Quintana finished with an all too familiar no-decision in a game against the Tigers, eventually won by the White Sox. Four of his last five starts have been quality, and the southpaw has allowed one homer in his last eight starts. Royals RHP Edinson Volquez at Twins RHP Kyle Gibson (-105, 8): Volquez lacked sharpness in Friday's 4-0 loss to the Rangers, some of which can be credited to the seven days between starts. He will look to get back on track with a quicker turnaround against Minnesota on Wednesday night. Gibson's 1.36 ERA was the best in the American League in May, but he struggled early against the Brewers on Friday. He gave up five runs on three homers in the first three innings, but settled down to go seven. Rangers RHP  Yovani Gallardo at A's RHP Jesse Hahn (-138, 7): Last time out, Gallardo battled through a start in which his command wasn't perfect -- he was pushing 90 pitches early in the fifth -- but he recovered for a quality start. He leads the team with 62 2/3 innings pitched. Hahn, who pitched seven innings of one-run ball in a win against the Tigers on Thursday, has limited opponents to just four runs over his last 22 innings spanning three starts. He's walked no more than one batter in those outings. Diamondbacks RHP Jeremy Hellickson at Dodgers LHP Brett Anderson (-165, 7.5): Hellickson has pitched at least six innings and given up three runs or fewer in each of his last four starts, the last three of which have been wins. He is 0-1 with a 7.56 ERA in two career starts against the Dodgers. Twice this season, Anderson recorded a quality start against Arizona, and twice Anderson has been left with a no-decision. Anderson will induce a steady diet of ground balls and he's only allowed four home runs this season.
