Red Sox OF Jackie Bradley Jr. sets extra base hit record, drives in seven

Red Sox outfielder Jackie Bradley Jr. turned in a career performance in Boston's rout of the Mariners.

Red Sox outfielder Jackie Bradley Jr. turned in a career performance in Boston’s 22–10 rout of the Seattle Mariners.

In what may stand as the single-game line of the entire season, Bradley went 5 for 6 at the plate with two home runs, three doubles and seven RBIs, setting the mark for most total bases in a game this season with 14.

Bradley Jr., 25, became the youngest major leaguer ever to record at least five extra-base hits in a game, also setting a Red Sox record with the five extra-baggers.

As SI's Cliff Corcoran notes, four of his total bases came off Mariners catcher Jesus Sucre, who entered to pitch the last inning after Boston broke the game open in the early innings and allowed three runs, including a two-run shot to Bradley. But forget that minor asterisk and bask in the net results for Bradley, renowned for his exceptional outfield defense but who has struggled to become an offensive contributor in the early stages of his career.

The Red Sox became the first team to record at least 15 runs and 21 hits in back-to-back games since the 1950 Red Sox. Boston chased Seattle ace Felix Hernandez with 12 hits and 10 runs in 2 1/3 innings. Bradley Jr. did all of his damage batting ninth.
