Each day of Wimbledon, Baseline will sum up the action with a photo gallery of the top surprises.

Halep Hauls Past Svitolina

With Serena Williams the heavy favorite against Barbora Strycova, Simona Halep vs. Elina Svitolina was meant to be a blockbuster. Svitolina held their career head-to-head lead 4-3, and their last meeting, in Doha this year, went three sets. Instead, Halep handily subdued the Ukrainian, 6-1, 6-3 to reach her first career Wimbledon final.

Serena Shuts Out Strycova

While Strycova was having the tournament of her career to reach the semifinals, winning just three games against Serena Williams was still a disappointment. The match lasted under an hour, coming in at 59 minutes. The Czech is now 0-4 against the 23-time Grand Slam champion.

Mixing It Up

Jelena Ostapenko and Robert Lindstedt are both excellent doubles players, but after the 22-year-old Latvian hit Lindstedt in the head, not once, but twice, this tournament, seeing them into the semifinals is a bit of a surprise. The duo bested Raluca Olaru and Franko Skugor, 6-7 (6), 6-3, 7-5 on Thursday.

Follow-Up Fail

In other mixed doubles news, top seeds Nicole Melichar and Bruno Soares couldn't back up their impressive win over Andy Murray and Serena Williams. The pair lost to Yang Zhaoxuan and Matwe Middelkoop, 6-4, 6-3.

American Youths

The juniors haven't gotten much notice this year, but a group of youngsters are representing the United States deep into the Slam. In the girls' event, Emmy Navarro and Alexa Noel are both in the semifinals—and don't play each other. On the boys' side, the American flag is being flown by No. 4 seed Martin Damm.
