It’s the final week of the regular season, with conference tournaments already getting under way in smaller leagues and starting early next week in the big conferences. That means the scramble is on for postseason positioning -- teams looking to secure their spots in their conference tournaments, strengthen their postseason dossiers and solidify their chances at hosting regionals.

Among the schools in that last bucket are some big names, and that’s where we’re focusing this week. Instead of highlighting one series above all others, this week it’s a look at several of the key series that will affect NCAA bids, seeding and hosting decisions.

One result of conference tournaments getting under way is that the usual weekend schedule for most teams gets a slight adjustment this week. The vast majority of weekend series will start Thursday -- rather than Friday -- to allow a little bit of a break before tournament play.

LSU at Vanderbilt

The stakes: Back-to-back series wins at Georgia and Arkansas have Vandy back as a projected host, but they’re more on the cusp than solidly set. LSU is likely safely in the field, and unlikely to host, but the Tigers are still playing for seeding.

When and how to watch: 8:00 p.m. ET on Thursday on ESPN2, 7:00 Friday streaming on SEC Network Plus, 2:00 Saturday on SEC Network.

Player to watch: There are a slew of Draft prospects in this series, but let's go with a guy who's still a year away. Vanderbilt outfielder Enrique Bradfield Jr. -- who you may remember from his recent steal of home -- is one of the most electric players in the country. His 41 steals are tied for third in Division I, and he also sports a .330/.424/.535 line at the plate with five triples.

Oklahoma at Texas Tech

The stakes: Depending on where you look, Tech is projected anywhere from a borderline top 8 national seed to not even hosting. A series win would obviously push them closer to the former than the latter. The Sooners appear solidly in the field, but are playing more for seeding within a regional than anything else.

When and how to watch: 7:30 p.m. ET on Thursday, 7:30 Friday and 3:00 Saturday, all streaming on Big 12 Now on ESPN Plus.

Player to watch: Pipeline has Texas Tech second baseman Jace Jung ranked No. 7 among Draft prospects. He’s at .358/.502/.668 with 53 walks against 28 strikeouts.

Maryland at Purdue

The stakes: Current projections have the Terps hosting, but it’s not a slam dunk. A ferocious non-conference schedule has them in good shape though. Despite four regional appearances in the past eight years, Maryland has never hosted.

When and how to watch: 6:00 p.m. ET on Thursday, 5:00 Friday and 1:00 Saturday. The opener will stream on BTN Plus, while Friday and Saturday’s games will both appear on Big Ten Network.

Player to watch: Maryland outfielder Chris Alleyne is one home run away from becoming the first 20-homer/20-steal player in Division I this season.

Florida State at North Carolina

The stakes: A series win over Miami last weekend has FSU on the cusp of hosting, but not everyone has them currently projected to be at home in the first week of June. UNC, meanwhile, currently appears to be on the right side of the bubble, but they’re not safely in the field yet.

When and how to watch: 6:00 p.m. ET on Thursday, 6:00 Friday, 2:00 Saturday. All games streaming on ACC Network Extra.

Player to watch: Seminoles lefty Parker Messick leads the country with 132 strikeouts. He’s ranked 49th on the MLB Pipeline Top 150 Draft prospects.

Gonzaga at San Diego

The stakes: Gonzaga seems to be right exactly on the cut line for hosting a regional, and if they don’t host, their choices may be pretty stark: a short trip to No. 2 Oregon State or a very long trip somewhere else. San Diego should be in the field, but they’re a bubble team at the moment.

When and how to watch: 9:00 p.m. ET on Friday, followed by a doubleheader starting at 4:00 Saturday, streaming on WCCSports.com

Player to watch: Gonzaga righty Gabriel Hughes comes in at No. 19 on the Top 150. He’s 7-1 with a 2.44 ERA, 115 strikeouts and 29 walks in 77 1/3 innings.
