The Blue Jays’ game of pitcher musical chairs continued on Monday, as the team sent Trent Thornton to Triple-A in order to open up room to recall Ryan Borucki.

Thornton, who was once in the mix as one of Charlie Montoyo’s high-leverage arms, has been relegated to mop-up duty. He was sent down at the end of August after some ugly outings and got called up for Sunday’s series finale in Baltimore and was immediately after allowing two earned runs over two innings of work against the Orioles.

Borucki has been in Triple-A since early August. He missed most of May, all of June, and half of July due to a forearm strain and was activated shortly after the All-Star break. In seven appearances over roughly a month after that injury, Borucki tossed six innings and allowed five earned runs on six hits and four walks. He also surrendered three home runs.

His stint in Triple-A has been up and down, as he’s tossed five outings, three of which were scoreless and two of which he got tagged up a little bit. Most recently, on Friday, Borucki tossed one inning against Syracuse and allowed two earned runs on one hit and a pair of walks.

As of right now, Tim Mayza is the only good lefty option in Toronto’s bullpen, so it would be great if Borucki could be anywhere near what he was last season or even pre-injury this season. Otherwise, the team will likely have to bring Tayler Saucedo back up to be the second lefty option behind Mayza.
