One of the Toronto Blue Jays’ top pitching prospects didn’t have much success in his most recent start
On Wednesday afternoon, Jake Bloss started the Buffalo Bisons games against the Iowa Cubs. There were some positives to take away from the game as a whole, namely Sean Keys’ multi-home run game, but Bloss’ start was not one of the positives.
Bloss entered the game with a 2-0 lead after Jonatan Clase hit a two-run home run for his fifth of the season. The starter’s first was fine, striking out Brett Bateman with a 96.7 mph fastball above the zone. After allowing a double, Bloss caught Moisés Ballesteros looking with an 89.4 mph slider at the bottom of the zone, then generated a ground out for a scoreless inning.
The start unraveled from there, though. Kevin Alcántara hit a lead-off double in the bottom of the second, then Owen Miller hit a game-tying two run homer. James Triantos hit a single, but was thrown out, followed by a ground out and fly out, the latter coming off the bat of former Blue Jay Ben Cowles.
Bloss allowed some more traffic in the bottom of the bottom of the third as well. He surrendered a lead-off single to Bateman, who promptly stole second. With an empty first base, BJ Murray walked, then the Cubs took the lead thanks to a Ballesteros single. A double play cashed in another run, before Bloss allowed a single and got a ground out to end the inning.
Returning for the bottom of the fourth, Bloss gave up a lead-off hit for the third consecutive inning, a double to Triantos. Bloss got his final batter to pop up, before being replaced by Devereaux Harrison. That run was eventually cashed in, and Bloss was tagged with the loss.
Over three and one-third innings, the right-handed pitcher allowed eight hits and gave up five earned runs, striking out two and issuing one free pass. With the performance, Bloss’ Triple-A ERA now sits at 8.59, while his season ERA stands at 5 after 27 innings pitched.
Diving a bit deeper into the stats, Bloss threw 65 pitches, 44 of which were for strikes. While his outing as a whole wasn’t encouraging, Bloss has continued to throw the ball hard. His four-seam fastball averaged 96.6 mph, up from his average of 93.4 mph last season. It also touched 98.1 mph.
Unfortunately, the heater only generated one whiff on 12 total swings, but that was the story of Bloss’ outing. His best pitch was the slider, which averaged 88.6 mph and generated two swings and misses on 11 total swings. The sinker also generated a whiff giving his just four whiffs in the game, good for a 13 whiff%.
Since the Blue Jays acquired Bloss in the Yusei Kikuchi trade nearly two years ago, he just hasn’t pitched well with the Bisons. Following the trade, he had a 6.91 ERA and 5.87 FIP in eight starts, though four of those starts saw him not allow a run over at least two and two-thirds innings. Before undergoing Tommy John surgery last season, Bloss had a 6.46 ERA and 4.76 FIP in 23.2 innings pitched with the Bisons.
Bloss remains on the Blue Jays’ 60-day injured list, and even though this rehab stint has been going on longer than a month, teams can request additional time for players recovering from Tommy John surgery. Whenever time is up, Bloss will have to be added to the 40-man roster, which means someone will probably need to be DFA’d.
The right-handed pitcher will be an option for the Blue Jays down the stretch, but at some point soon, he has to start finding success at the Triple-A level. Bloss’ stuff sure does look good, though.
