37 runs in their first 2 games after he took over, and recording a .636 winning percentage through the end of September, compared with a .439 winning percentage on the season under Farrell. A high point came near the end of the season when the Red Sox posted a six-game winning streak and moved up to third place in the AL East. However, the team lost their last four games and ultimately finished at the bottom of their division for the second year in a row. On October 1, 2015, it was reported that, if healthy, Farrell would return to his position as Red Sox manager at the beginning of the 2016 season, leaving Lovullo's position with the organization uncertain after his performance as interim manager. It was announced that Lovullo would resume his bench coach duties for the 2016 season on October 4, 2015, with Farrell returning as manager. Lovullo was also given a two-year contract extension in exchange for forgoing his right to pursue managerial job offerings. The 2016 season was Lovullo's fourth consecutive season with the Red Sox, and his sixth straight overall as an aide to Farrell. Arizona Diamondbacks manager Mike Hazen, who had worked with Lovullo with both the Indians and Red Sox, was named the new general manager of the Arizona Diamondbacks on October 16, 2016. Almost three weeks later, on November 4, Hazen appointed Lovullo to replace Chip Hale as the Diamondbacks' manager for the 2017 season. Hazen hired Lovullo over fellow managerial finalist Phil Nevin. In his first season as manager, he guided the team to the postseason, winning the NL Wild Card Game and finishing with a record of 93 wins and 69 losses, a 24-game improvement for the team from 2016. For his efforts, Lovullo was named 2017 National League Manager of the Year. During the April 7, 2018 game against the St. Louis Cardinals, Lovullo was ejected in the second inning after an argument with umpire Tim Timmons resulted in a fight with Cardinals catcher Yadier Molina by calling him a choice word; the Diamondbacks won that night, 4-1, thus making it Lovullo's 100th managerial victory, as well as marking him the fastest manager in Diamondbacks history to win 100 games with the team. Lovullo and Molina were suspended for a game. In January 2019, Lovullo and the Diamondbacks agreed to a two-year contract extension, through the 2021 season.
