Zach Eflin, who opened the season on the DL, will make his first major league start of the season Tuesday for the Phillies when they play the Mets in New York. After making one rehab start with Clearwater, Eflin was activated from the DL and optioned to Lehigh Valley, who he pitched for last Tuesday against the Scranton/Wilkes-Barr RailRiders.
In his two minor league starts, Eflin has thrown 10 scoreless innings, allowing just six hits and walking three while striking out 10 of the 38 batters that he has faced. He made his major league debut last season with the Phillies, making 11 starts and posting a 5.54 ERA with a 3-5 record.

Over the winter, Eflin had both knees operated on and needed a little extra time to get ready this Spring, which is why he opened the year on the DL. During Spring Training, Eflin had told reporters that he felt like he was pitching with new legs.
If all goes as planned, Eflin could be in the majors long-term, because it's likely that Clay Buchholz (partial tear in the flexor tendon) will miss considerable time and could wind up going on the 60-man DL. Until Eflin departs, Lehigh Valley actually had six starters on their roster, which they needed because of two double-headers in the first 10 days of the season. As things have played out for the IronPigs, Eflin was the logical choice to replace Buchholz.
Meanwhile, Lehigh Valley can get their rotation back into a normal grind because of off days on both Sunday and Monday. They open a six-game homestand against Columbus and Toledo starting Tuesday night.
