Jason Marquis got released by the Twins in May after pitching about as poorly as a big leaguer could possibly pitch, starting seven games with an 8.47 ERA, .371 opponents’ batting average, and more walks (14) than strikeouts (12) in 34 innings.
He quickly signed a minor-league deal with the Padres and joined their rotation after just one Double-A start. And after out-dueling Tim Lincecum last night Marquis now has a 3.48 ERA in 10 starts for the Padres.
And before you go attributing all that success to Petco Park, consider that last night’s win over the Giants came on the road and Marquis actually has a better ERA on the road (3.38) than at home (3.60) as a member of the Padres.
Perhaps the most startling aspect of Marquis’ turnaround is that he’s racking up strikeouts for the first time since … well, ever. Marquis has always had one of the lowest strikeout rates in baseball, never whiffing even 7.0 batters per nine innings in a season, yet since joining the Padres he has 56 strikeouts in 62 innings.
How does a 33-year-old with a 4.60 career ERA go from posting an 8.47 ERA and 12/14 K/BB ratio in 34 innings for the Twins to immediately posting a 3.48 ERA and 56/17 K/BB ratio in 62 innings for the Padres? Having watched all seven of Marquis’ starts for the Twins it literally doesn’t seem possible.
