Jackson was placed on the 10-day injured list Tuesday due to a lower-back injury, Scott Mitchell of TSN.ca reports. Jackson was tagged for seven runs during Monday's start against the Angels, though the back issue may have played a role in his poor showing. The Blue Jays have yet to issue a timetable for his return, but he'd miss just one turn through the rotation if he can return after the 10-day minimum.
Jackson (1-5) took the loss Monday as the Blue Jays were downed 10-5 by the Angels, surrendering seven runs on six hits -- including three home runs -- and two walks in only two-thirds of an inning. He failed to strike out a batter. After Derek Law turned in a perfect first inning as the Jays' opener, Jackson entered the game and served up a homer to Justin Upton on the first pitch he threw, setting the stage for an absolutely disastrous outing. The veteran right-hander came into Monday with a double-digit ERA and somehow made it worse, and he now sits with a 12.43 mark, and a mind-boggling 4.3 HR/9, through 25.1 innings. Toronto doesn't have a lot of options to replace Jackson, but even in a rebuilding season it seems inconceivable that they'd continue to send the 35-year-old to the mound every fifth day given his performance so far.
Jackson will work as the primary pitcher Monday against the Angels. Derek Law will serve as the opener in front of Jackson for a second straight week. The veteran right-hander picked up a win as the primary pitcher his last time out, allowing two runs on four hits and two walks while striking out two across five innings.
Jackson (1-4) allowed two earned runs on four hits, two walks and a wild pitch while striking out two across five innings to earn the win Wednesday against the Orioles. Jackson took over in the second inning and worked with little trouble until losing his command in the fifth inning. He began the frame by walking the first two batters he faced and ultimately allowed a run to cross the plate on a wild pitch. Still, this was one of Jackson's better efforts of the season and the first time he's worked five innings since May 20 -- a span of three starts. Even with this performance, he has a 10.22 ERA and 2.03 WHIP across 24.2 innings for the season. He'll likely pitch again Monday against the Angels, though it remains to be seen if he works as a traditional starter or a primary pitcher.
Jackson will work as the primary pitcher Wednesday against the Orioles, Shi Davidi of Sportsnet.ca reports. Jackson was originally scheduled to start, but he'll instead follow an opener (Derek Law) in an effort to get him past the top of the order out of the gate. The veteran right-hander has made five starts for the Blue Jays this season, struggling to an 11.90 ERA, 2.24 WHIP and 15:8 K:BB in 19.2 innings.
