Team USA is closing fast. More medals on Wednesday brought the United States ever closer to the top three among nations in Rio’s overall medal count, and there are opportunities to add medals today. If you’re looking for the “what to watch from Rio,” this is the place for the next four days. The action can be viewed live on TeamUSA.org and broadcast on NBC and NBCSN. Click here for a full viewing schedule. (All times below are ET.)

Thursday, Sept. 15

Track and Field

Set an alarm for 6:24 p.m., at which time we can all look forward to the “McRelay.” The women's 4x400-meter T53/54 will draw from a pool of Team USA’s fastest wheelchair track stars, including the incomparable Tatyana McFadden (T54), her sister, Hannah McFadden (T54), Amanda McGrory (T54) and Chelsea McClammer (T53), plus Cheri Madsen (T54) and Shirley Reilly (T53). Tatyana McFadden already has four medals in Rio, and she’ll have another shot at gold a few hours earlier when she competes in the women's 5,000-meter T54 final (4:30 p.m.). McClammer, already with a silver and bronze in Rio, and McGrory, with a silver to her credit, are also in the 5,000 field. Two days prior, the trio swept the 1,500 (McFadden-McGrory-McClammer). The relay, though, sets up as one of the most impressive sub-four minutes of the Games.

Wheelchair Basketball

Beginning with the first day of competition, back on Sept. 8 with a 75-38 win over host Brazil, Team USA’s men have been aiming for a successful conclusion to their Rio experience with equaling or building on a bronze in London. Wins of 77-52, 93-44, 92-24 and 65-48 followed, and a comeback win on Wednesday — a 13-0 run to begin the second quarter and a 24-4 run in the third erased an 18-12 first-quarter deficit — sent the United States to today’s semifinals against Turkey (8 p.m.).

Sitting Volleyball

What stands between Team USA's women and a guaranteed medal? The host country. And in a night match, no less, among Rio’s final four, with the United States facing Brazil in this evening’s sitting volleyball semifinal (7:30 p.m.). In the earlier match, China plays Ukraine, potentially setting up a highly anticipated China-Team USA final that would give the United States a chance to avenge its only loss of the tournament. The United States is led by four-time Paralympian Lora Webster and captain Heather Erickson, a three-time Paralympian.
