On Wednesday, Indians manager Manny Acta penciled in only two right-handed hitters in his lineup. The addition of Hottovy gives the Royals another option to counter the abundance of lefties and switch-hitters in Cleveland's order.
"It gives us another option and balances our 'pen out," Royals manager Ned Yost said. "We have three lefties, three righties and a closer."
Hottovy, 30, was a fourth-round pick by the Red Sox in the 2004 First-Year Player Draft. He appeared in eight games for Boston last season, his first in the big leagues.
"It's always kind of a surprise when you get the opportunity," Hottovy said. "I was throwing well. I knew that if I took care of business and kept working on what I needed to do, the opportunity would come. This early in the season, you just never know. I'm excited to be here to help the team in any way that I can. I'm just looking forward to getting out there and getting rolling."
In seven appearances with Omaha, Hottovy went 1-0 with a 2.70 ERA. Jeffress had appeared in just two games with Kansas City, tossing one scoreless inning.
