Before each day's play at the BNP Paribas Open, we'll preview three must-see matches.

The second seed was down 2-5 to start, before finding his way past good friend Filip Krajinovic on Monday.

Also, Elena Rybakina makes her Top 10 debut, Magda Linette cracks the Top 30 and Ben Shelton soars into the Top 50.

The Greek player—who also pledged to build a school in Victoria with his prize money should he lift the trophy—is back into the semifinals for the third year in a row.

Plus: Three other quarterfinal plays.

Each day, we'll preview three must-see matches.
