Meyers to undergo testing: Astros center fielder has been out in recent days due Tommy Doyle Jersey to right calf tightne s but was penciled back into the lineup for Wednesdays game. Unfortunately, Meyers was lifted the game before it even began. The 29-year-old aggravated the injury while jogging out to center field and was helped off the field by a trainer before the first pitch was even thrown. As noted by , manager Joe Espada told reporters after the game that Meyers would undergo testing after the game and the club would know more about his status today. The Astros already have eight position players on the injured list. Meyers would be a ninth, if he needs an IL stint. Because of that slew of injuries, Houston doesnt have any additional minor league position players on the 40-man roster at this point. They need to reinstate from the paternity list, however, which could fill Meyers spot. That would likely leave center field to be manned by and , although is currently on a minor league rehab a signment. 2. Doubleheader in Baltimore today: Yesterdays game between the Mets and Orioles was postponed due to rain. wrote yesterday about the makeup game, which is scheduled to take place as part of a split doubleheader later today.

Yankees eyeing a sweep: Todays game between the Yankees and the Mariners will have a significant impact on the AL Wild Card picture. The Yankees are looking for a sweep after taking the first two games in this weeks set, but theyll have an uphill battle in order to secure that third win. (7.45 ERA in five starts) is on the mound at 7:05pm local time for the Bronx Bombers today, and while hes looked better than that ERA would suggest since returning from the injured list hell be tasked with taking on young Mariners star , who has a 2.77 ERA in 17 starts this year.
