Justin Upton began his baseball career with the Arizona Diamondbacks in 2007, at the age of 19. By 2009, he was the starting leftfielder and an All-Star for the first time, after hitting over .300 for the first time and belting more than 25 home runs.

Upton continued to perform well, with a decent 2010 season where he hit 17 home runs and had an OPS of .799, and an excellent 2011 season where he hit 31 home runs, had an OPS of .898, and finished fourth in the MVP voting. He won his first Silver Slugger award that year.

In 2013, Upton was traded to the Atlanta Braves, where he played with his brother Melvin for two years and added another Silver Slugger award to his resume. He hit 27 home runs and drove in 102 runs during his time in Atlanta.

After being traded to the San Diego Padres in 2015, Upton continued to perform well and was named an All-Star once again, hitting 26 home runs and having an OPS of .790. However, he became a free agent at the end of the season and signed with the Detroit Tigers.

Upton had a productive 2017 season with the Tigers, hitting 31 home runs and being on pace for more. However, the Tigers traded him to the Los Angeles Angels mid-season, where he had his best year yet. In 2018, Upton hit 35 home runs, had 109 RBIs, and an OPS of .901. He earned his fourth All-Star selection and third Silver Slugger award that year.

Unfortunately, Upton struggled with patellar tendinitis in 2019, which greatly impacted his performance. He played for the Angels until 2021 and had a brief stint with the Seattle Mariners in 2022. Throughout his career, Upton amassed 1,754 hits, 325 home runs, and 1,003 RBIs.

Joe Smith appeared in a whopping 866 Games in the Majors, all of which from the bullpen, with most in middle relief. 

A 15-year veteran, Smith played for eight different teams, but his best success with Cleveland, the team he played six years for and had nearly half of his career bWAR (6.4 of 12.9) and had three consecutive seasons of a sub-3 ERA (2011-13).  With that said, Smith’s best season was right after when he joined the Los Angeles Angels when he went 7-2 with 15 Saves and a 1.81 ERA.

Smith also pitched for New York (NL), Chicago (NL), Toronto, Houston, Seattle and Minnesota, with an overall record of 59 and 34, 30 Saves and 176 Games Finished.

Jed Lowrie is a 14-year MLB veteran infielder who started his career with the Boston Red Sox. However, his most successful stint was with the Oakland Athletics. After playing for the Red Sox for four years (from 2008 to 2011), he was traded to Houston, who then dealt him to Oakland after a year. Despite never having played over 400 plate appearances in a season, Lowrie became Oakland's full-time shortstop and managed to hit 175 times with a batting average of .290. The next year, he recorded 125 hits with a .249 batting average. After becoming a free agent, Lowrie returned to the Astros but was soon shifted from shortstop to third base in favor of Carlos Correa, who won the Rookie of the Year. He was then traded back to Oakland, where he had his best season, being selected as an All-Star and achieving career-highs in home runs (23), runs batted in (99), and OPS+ (121).

Lowrie then signed a two-year contract with the New York Mets, but knee problems limited him to only nine games, and he missed the entire 2020 season. Later, he rejoined Oakland for two more seasons, finishing his career with 1,185 hits and 121 home runs.

Greg Holland was one of the best relief pitchers in the 2010s and played a crucial role in the success of the Kansas City Royals during that time.

Holland was drafted by the Royals in 2007 and made his debut for the team in 2010. The following year, he proved himself with an impressive performance, posting a 1.80 ERA and a WHIP of less than one (0.933) over 60 innings. After another strong season in 2012 (2.96 ERA), Holland became the Royals' ninth-inning specialist.

From 2013 to 2014, Holland was one of the top closers in the league, finishing ninth in Cy Young voting both years with ERAs under 1.5 and WHIPs under one. He was named the 2013 American League Pitcher of the Year by the Sporting News, and in 2014, he helped the Royals reach the World Series. During the playoffs, Holland had seven saves and allowed only one run in ten innings.

Though not as dominant in 2015, Holland remained effective until he suffered a torn UCL injury. Despite his absence, the Royals went on to win the World Series that year. Holland missed the entire 2016 season to recover from his injury. When he was ready to return, he became a free agent and signed with the Colorado Rockies, where he won the AL Comeback Player of the Year award and his first Saves Title (41). He was also selected to the All-Star team for the third time.

However, Holland was unable to recapture his earlier success and spent the next five years moving from team to team, playing for St. Louis, Washington, Arizona, a second stint with the Royals, and Texas. In total, he amassed 220 saves.
