As the A's prepare to close out the regular season with three games against the Angels, several players have a chance to reach major milestones. Here are the numbers to keep an eye on this weekend.

50 - Khris Davis is three home runs away from the big 5-0. He would become just the third player in A's history to reach the mark, joining Jimmie Foxx and Mark McGwire. Davis is also trying to become the first A's player to lead the majors in homers since McGwire hit 52 in 1996. Davis leads Boston's J.D. Martinez by five home runs entering the weekend.

128 - KD could also potentially catch Martinez for the major league RBI lead. Davis has driven in a career-high 121 runs so far this season, second in MLB behind Martinez's 127.

100 - Jed Lowrie enters the weekend with a career-high 96 RBI, just four away from triple digits. If he can get there, he would become the seventh American League player to do so this season.

40 - Lowrie is also just three doubles away from reaching 40 for the second straight year and third time in his career. Last season, he notched a career-high 49 two-baggers.

30 - Matt Olson needs one more home run to reach 30 for the season. Stephen Piscotty, currently at 26, has a little more work to do. Both Olson and Piscotty's totals already represent career highs.

86 - Piscotty is one RBI away from a new career best. His 85 RBI match his previous high, set in 2016 with the St. Louis Cardinals.

76 - Marcus Semien also has an outside chance at a new RBI mark. He enters the weekend with 68, so he would need seven more to match his previous high and eight to break it.

100 - Davis and Matt Chapman both have a shot at 100 runs scored. Chapman enters the final series with 98, while Davis has 97. Both totals already represent career highs.

.300 - Rookies Nick Martini and Ramón Laureano have a chance to hit .300 for the season. Martini is already north of the mark at .306, while Laureano is batting .295.

.400 - Martini also has a chance at a .400 on-base percentage, an incredible achievement for any player, let alone a rookie. Martini enters the weekend at .401.

0.79 - Blake Treinen is having a historically great season. His 0.79 ERA would be the best in major league history among pitchers who threw at least 75 innings. Treinen also has an outside shot at reaching 40 saves, as he enters the weekend with 37, although it is highly unlikely Bob Melvin would use him three days in a row leading into the playoffs.
