A first-round draft pick out of Norwell in 2007, when healthy, Parker has been a top-notch pitcher. His career mark is 25-16 with a 3.68 ERA in 62 starts and 275 strikeouts over his three years with Oakland, but he’s had to undergo three Tommy John surgeries and is recovering from the third. Among his highlights, Parker threw seven innings of no-hit ball against Texas on June 4, 2012, he started two games in the 2012 playoffs against Detroit, and finished fifth in the Rookie of the Year voting. In 2013, he threw 19 consecutive starts without a loss and started another playoff game.
