Houston Astros shortstop Jeremy Pena (knee) remains out of the starting lineup for Saturday's game against the Washington Nationals. He exited early during Thursday's game due to knee discomfort and hasn't played since then. At the moment, the Astros are considering Pena day-to-day. This doesn't sound like something that will require a trip to the injured list, but fantasy managers should stay tuned for more updates. Aledmys Diaz will cover shortstop and bat seventh versus righty Erick Fedde on Saturday.

Houston Astros manager Dusty Baker said that shortstop Jeremy Pena (knee) probably will not play on Friday in the series opener against the Washington Nationals. Pena left the game against the Minnesota Twins early due to discomfort in his right knee, and fantasy managers should consider him day-to-day for now. With Aledmys Diaz also dealing with an undisclosed injury, it'll likely be Niko Goodrum as the team's starting shortstop on Friday against the Nats. The 24-year-old has done his best to fill the shoes of Carlos Correa, who departed for Minnesota in free agency. Pena is hitting .245/.318/.490 with an .808 OPS, six home runs, 17 RBI, 17 runs scored and a stolen base in his first 28 major league games, so fantasy managers are hoping he can avoid a trip to the injured list.

Houston Astros shortstop Jeremy Pena is getting the day off on Wednesday as the team takes on Matt Brash and the Seattle Mariners. Aledmys Diaz will be covering shortstop and batting seventh in the game. Pena has been a solid contributor for the Astros' offense this year. Over 23 games, he's slashing .229/.301/.470 with five home runs, 14 RBI and 14 runs scored. The rookie has recorded a barrel on 10 of his 62 batted balls, good for a 16.1% barrel rate that ranks in the 91st percentile. His .263 xBA and .566 xSLG suggest there's plenty of room for growth in his slash line. The positional depth at shortstop makes him a bit tough to roster in some standard leagues, but in AL-only leagues and extra deep leagues, he's a borderline must-roster player at this point.
