Oliver, 42, agrees to return to Blue Jays

Darren Oliver will reach an even 20 years in the major leagues, as the left-handed reliever agreed to return to the Toronto Blue Jays.

After last season, the Blue Jays picked up Oliver's $3 million option for 2013. However, Oliver hadn't confirmed until Tuesday whether he intended to continue his career at age 42.

In 2012, Oliver made 62 appearances for Toronto, serving mostly as a one- or two-out specialist. He compiled a 3-4 record with two saves and a 2.06 ERA in 56 2/3 innings.

While left-handed specialists are expected to shut down opposing left-handed hitters, Oliver was effective against all batters. Left-handers hit .234 against him, while right-handers batted a paltry .196.

Oliver began his major league career in 1993 with the Texas Rangers, and he has since had stints with the St. Louis Cardinals, Colorado Rockies, Boston Red Sox, Florida Marlins, Houston Astros, New York Mets and Los Angeles Angels. He's pitched three separate stretches for Texas.

Overall, Oliver has a 115-94 record with seven saves and a 4.53 ERA in 716 appearances (229 starts). He's pitched in two World Series, losing with the Rangers in 2010 and 2011.
