Renteria does have managing experience in Chicago, leading the Cubs to a 73-89 record in 2014. General manager Rick Hahn claimed that there were no better candidates for the position.
Ventura spent five seasons with the White Sox, going 375-435. His best season was his first in 2012, where he lead the team to an 85-77 record, just barely missing out on the postseason. The team got off to a quick 23-10 start this year, but ended the season at 78-84 after going 55-74 the rest of the way. Ventura's stint with the team ended with a 6-3 loss to the Minnesota Twins on Sunday.
Another manager that parted ways was Walt Weiss of the Colorado Rockies, who chose to step down with his contract up. He spent four seasons with the team, most recently going 75-87 this year. This position was a major jump for him, as he was just a high school coach at the time he took the job in November of 2012.
Weiss did play four seasons with Colorado, from 1994-1997, and served as a special assistant from 2002-2008. The Rockies were in contention for much of the first half, but struggled in close games, finishing 24-36 in games decided by two runs or less, including 28 blown saves.
Despite the potent offensive lineup they put out there, they just could not hang on to leads, struggling both defensively, and on the mound. Weiss had a lot of good things to say about his now former team, stating "there's a lot to feel good about."
The Arizona Diamondbacks made their own decision on their managerial change, firing manager Chip Hale and general manager Dave Stewart on Monday afternoon. The team finished 69-93, 22 games out of first place in the NL West.
Stewart came in as GM in 2014, lasting just three seasons, with Hale coming in right after the 2014 campaign. The manager compiled a record of 148-176 in his two seasons.
The organization made a couple of questionable moves by acquiring pitcher Shelby Miller, while giving up young shortstop Dansby Swanson, and outfielder Ender Inciarte. Miller struggled this season with Arizona, going 3-12 with a 6.15 ERA.
The team did sign Zack Greinke last off-season to a $206 million contract, and he struggled despite recording a team-high 13 wins. The acquisition of Greinke, as well as a reliable starting nine, gave the team high hopes heading into 2016. Hale's inability to capitalize on that potential lead to his departure just one day into their off-season.
