 Biographical Information
Alfredo Aceves was signed by scout Tony Arias for the Toronto Blue Jays in 2001. After pitching 10 games for the DSL Blue Jays in 2001, his contract was sold to the Leones de Yucatán. Aceves pitched for Yucatan from 2002 to 2005 and Sultanes de Monterrey in 2006-2007. He then signed as a free agent with the New York Yankees for $450,000 on the recommendation of scout Lee Sigman.
Aceves became the Boston Red Sox's closer by default at the start of the 2012 season, after Jonathan Papelbon's departure via free agency and an injury suffered in spring training by his expected successor, Andrew Bailey. As 2011's set-up man, Daniel Bard, had just been converted into a starter, new BoSox manager Bobby Valentine found himself with few viable options for the job. Aceves had been a middle reliever and spot starter the previous year, having an outstanding season with a 10-2 record and a 2.61 ERA in 55 games. However, in his first appearance on April 5th, facing the Detroit Tigers, he gave up the game-winning hit to Austin Jackson, the only batter he faced, then in his second game on April 8th, he came in to protect a 10-7 lead in the 9th, and immediately gave up a pair of singles and a game-tying home run to Miguel Cabrera; he left the game again without having retired anyone. He settled down after that inauspicious start, however, and while his ERA remained high, he began picking up saves on a regular basis. Not wishing to miss out on the soap opera that was the Red Sox season that year, he threw a tantrum on August 24th, when he stormed into manager Valentine's office to complain that the recently returned Bailey had been preferred to him in the save situation against the Kansas City Royals in that day's game. The meeting was less than friendly, and the next day, the Sox suspended him for three games for "conduct detrimental to the team". He was then unavailable as they suffered another bullpen meltdown, blowing a 9-3 lead against the Royals to lose, 10-9, in 12 innings. Not only was he suspended, but he was also forbidden from taking the team's airplane on a trip to the West Coast after the three games, being asked to find his own way to Anaheim, CA but to be sure to report in time for the team's next game. The Sox also called up Bard from AAA on August 30th, and announced that Aceves would would be used in longer situations during the last month, with the possibility of being made a full-time starter the following year. Indeed, he went 0-1 with a 7.56 ERA in 8 September appearances, most of them in mop-up duty. He finished the season at 2-10, 5.36, racking up 25 saves in spite of his well-publicized troubles.
After a couple of appearances out of the bullpen at the start of 2013, Aceves was indeed moved to the starting rotation, but the results were less than great. He did win his second start on April 17th, but that was in spite of allowing 3 runs in 5 innings, then he was smoked by the Oakland Athletics on April 23rd, giving up 8 runs in 3 1/3 innings in a 13-0 loss. His record stood at 1-1, 8.66 at that point and the Red Sox decided to send him down to the AAA Pawtucket Red Sox after the game.
