 Biographical Information
Jake Diekman made it to the big leagues in 2012.
Diekman was picked by the Philadelphia Phillies in the 30th round of the 2007 amateur draft. The scout was Jerry Lafferty. He made his pro debut with the GCL Phillies and did well enough (1-3, 2.92) to earn a promotion to the Williamsport Crosscutters, where he had a 2-1, 2.25 record. He began 2008 with the Lakewood BlueClaws and was 3-5 with a 5.42 ERA and .310 opponent average. He was demoted back to Williamsport, where he went 1-4 with a 4.40 ERA. He spent 2009 with Lakewood, going 2-0 with two saves and a 4.04 ERA in a new relief role. After a strong 2010 start with the BlueClaws (2-0, 1.90, 30 K in 23 2/3 IP, albeit with 15 walks), he was promoted to the Clearwater Threshers and was 0-2 with a 3.66 ERA in 24 games. He allowed a .187 average for the year with 56 strikeouts in 55 2/3 IP but also with 38 walks. He played in the Arizona Fall League.
The Nebraskan was 0-1 with 3 saves and a 3.05 ERA for the 2011 Reading Phillies, holding lefties to a .099 average (9 hits in 91 at-bats) and whiffing 83 in 65 innings. He tied Ricky Brooks for 4th in the Eastern League with 53 pitching appearances. He allowed only one earned run and struck out 14 in 11 1/3 IP for Scottsdale in the Arizona Fall League. He opened 2012 with the Lehigh Valley IronPigs and was excellent after 13 games (1-0, 5 Sv, 1 R in 15 1/3 IP, 22 K to 3 BB).
Diekman was then called up to the big leagues along with veteran Raúl Valdés; they replaced Joe Savery and Brian Sanches on the Phillies. In his MLB debut, he relieved Chad Qualls in the top of the 9th with two men in scoring position, two outs and a 3-3 tie, a pressure-filled situation. He came through, striking out fellow rookie Marwin Gonzalez. In the 10th, he retired Jed Lowrie on a fly then whiffed both Jose Altuve and Jordan Schafer. Diekman got the win when Hunter Pence homered in the bottom of the inning.
