Cardinals left-hander Tyler Lyons yielded one run while striking out six Wednesday for Triple-A Memphis.
He allowed five hits (though three were doubles) and one walk, lowering his season ERA to 3.32. Lyons is likely to take Joe Kelly's (hamstring) rotation spot and could make a few starts for St. Louis. Lyons put up a 4.75 ERA (though a 3.73 FIP) in 12 appearances (eight starts) for the Cardinals in 2013, striking out 43 batters in 53 innings (7.3 K/9), so he could be a good streaming option in deeper fantasy leagues.
Casey Janssen has been shut down temporarily with renewed discomfort in his lower back.
Janssen threw a scoreless rehab inning on Tuesday but woke up the next day with a sore back. He has been on the disabled list since the end of spring training with a strained muscle in his lower back and abdomen. Sergio Santos remains the Blue Jays' closer.
Jose Reyes (hamstring) is now expected to rejoin the Blue Jays on Saturday in Cleveland.
The weather looks iffy for Friday's series-opener with the Indians, and the Jays don't want to risk Reyes returning to a cold and muddy infield. The 30-year-old shortstop left Toronto's series-opener on March 31 with hamstring inflammation. He did not suffer a strain.
Tigers right-handed pitching prospect Jake Thompson allowed his first run of the season for High-A Lakeland on Wednesday, bringing his ERA to 0.48.
The 6-foot-4, 235-pound Thompson has struck out 17 batters in 18 2/3 innings in 2014 while allowing 10 hits, five walks, and three hit batsmen. Thompson, who was the Tigers' second round pick in the 2012 draft, has averaged 9.6 K/9 for his professional career. Thompson projects to be a mid-rotation starter with an 89-92 mph fastball, a developing slider, and a work-in-progress change-up.
Corey Hart is playing right field for the first time with the Mariners Thursday afternoon vs. the Rangers.
Hart missed the entire 2013 season after undergoing dual knee surgeries, so he has been limited to DH duties in his 10 starts so far with Seattle. The 32-year-old has displayed good power in the early going, boasting three home runs in 43 plate appearances.
Nationals right-handed pitching prospect Lucas Giolito struck out six batters in five shutout innings for Low-A Hagerstown on Wednesday night.
Giolito allowed two hits, walked two batters, and induced one doubleplay ball. He was matched up against Orioles pitching prospect Hunter Harvey, who could be his opponent in Battle of the Beltways for years to come. Giolito featured a fastball that sat between 92-94 mph with his 81-84 mph change-up that has great arm-side fade and vertical drop. Giolito has 15 strikeouts through 13 innings, and has allowed only four runs (three earned), nine hits, and four walks. The Nationals will continue to keep Giolito's pitch counts in check as he recovers from Tommy John surgery, so it is doubtful that he will rack up substantial innings in 2014.
Evan Gattis is not in the Braves' starting lineup for Thursday's series-finale against the Phillies.
Gerald Laird is starting behind the plate. Gattis, who's batting .375 with a 1.135 OPS and four home runs in 10 games this season, is simply getting a day of rest.
Orioles pitching prospect Hunter Harvey struck out seven batters while throwing six shutout innings for Low-A Delmarva on Wednesday night.
Harvey allowed one hit and one walk, but hit two batters, throwing 60 of his 103 pitches for strikes as he locked horns with fellow elite pitching prospect Lucas Giolito. Harvey has allowed three runs, eight hits, and four walks while striking out 18 and hitting three batters in 17 innings this season. His fastball sits 92-94 mph, his curveball is 78-81 mph with a hard downward snap, and his changeup is 85 mph with downward sink. The front-line arsenal is there.
